概述

之前的文章我们介绍过如何将freeswitch做成docker镜像，也使用命令行模式正常启动了fs的docker容器。

但是当我们需要同时管理多个docker容器的时候，还是使用docker-compose更简单。

环境

CENTOS 7

docker engine：Version 25.0.3

Docker Compose version v2.24.6

centos docker：7

freeswitch：v1.6.20

docker-compose安装

使用docker-ce的yum源安装。

sudo yum remove docker \

                  docker-client \

                  docker-client-latest \

                  docker-common \

                  docker-latest \

                  docker-latest-logrotate \

                  docker-logrotate \

                  docker-selinux \

                  docker-engine-selinux \

                  docker-engine

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

sudo yum makecache fast

sudo yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin

ll /usr/libexec/docker/cli-plugins/docker-compose

sudo ln -s  /usr/libexec/docker/cli-plugins/docker-compose  /usr/bin/docker-compose

sudo ln -s  /usr/libexec/docker/cli-plugins/docker-compose  /usr/local/bin/docker-compose

docker-compose version

Docker Compose version v2.24.6

docker-compose.yml

docker-compose使用yaml配置文件来管理docker容器，配置好yaml文件之后就可以很方便的使用了。

cat docker-compose.yml

version: '2'

    depends_on:

      - freeswitch

    profiles:

      - cb

# sudo docker-compose --profile cb up -d

简单介绍一下配置文件。

启动两个docker容器，freeswitch和cb，cb为可选，使用“cb”profile启动。

测试

使用上面的yml文件启动容器。

$ sudo docker-compose --profile cb up -d

总结

docker-compose简化了多个docker容器的管理难度。

对于docker集群的部署，使用docker-compose很方便。
